SCRAPER FOR WHEELS OF AGRICULTURALIMPLEMENTS.

SPECIFICATION forming part of Letters Patent No. 747,813, dated December22, 1903. Application filed July 1 3. 1903. Serial No. 165,321. (Nomodel.)

be attached to any such implement by any suitable bracket.

Figure lis an end elevation of the scraper.

' Fig. 2 is a horizontal section on line 2 2 of Fig. 1, while Fig. 3 isa rear elevation of Fig. 1. Figs. 4 and 5 are detached detail views ofpart of this invention.

Referring to the drawings, it will be seen that my scraper consists,essentially, of a disk 1, revolubly mounted upon one end of a bracket orarm 2, bent to any suitable shape and springing from the frame 3 of,say, a seed-drill, said disk or bracket being capable of adjustmentinorder that it may be brought up against the periphery of the wheel 4.The disk may be flat or concavo-convex, and the friction against theimplement-wheel tends to keep it comparatively sharp and runs free thatis to say, is not driven by gearing or the like, but, on the contrary,is driven by frictional contact with theimplement-wheeL.

The disk, which is set at any desirable angle to the periphery of thewheel, has a central boss 5 and is mounted on one end of a spindle 6,rigidly secured in a boss 7 on the end of the bracket 2, said spindle 6being at the side of the wheel. This spindle 6 is squared, as at 8,about its center andis threaded at each end and provided with a shoulder9, as clearly illustrated in Fig. 4. The squared part 8 of the spindlefits into a slot 10 in the boss 7 of the bracket, so that the disk maybeadjusted with relation to the wheel and held rigidly in position bytightening the nuts 11. The disk is secured in position on the bracketabout the height of the'axle of the implement-wheel, as shown. The frame3 of the implement has a slot 12, in which the bolt 13,

which secures the bracket to the frame, may be moved, so that the diskcan be adjusted with relation to its contiguity to the periphery of thewheel. The disk may be also adj 11sted by placing washers 14 between theboss of said disk and-the-shoulder9 of the spindle. As the wheel of theimplement revolves the disk is also rotated by the friction against theperiphery of said wheel, whichis thereby.

soil and thoroughly scraped.

It must be understood that I do not confine myself to the shape of thebracket shown, as it must naturally conform itself with regard toposition and height of the frame of the implement to which the inventionis attached.

Having now particularly described and ascertain ed the nature of mysaidinvention and in what manner the same is to be performed, I declarethat what I. claim is 1. An improved scraper for wheels of agriculturalimplements, consisting of a freelyrotatable disk revolubly mounted-inproximity to the periphery ofthe implement-wheel and at a right anglethereto, said disk being arranged to be rotated by frictional contactwith the implement-wheelsubstantially as set forth and illustrated.

2. An improved scraper for wheels of agriculturalimplements, consistingof a freelyrotatable disk adjustably mount-ed at a right angle to theimplement-wheel on a spindle at one side of the periphery of saidimplementwheel, said spindle being carried by an adjustable bracketfitted to the implementframe, the said disk being rotated by frictionalcontact with the implement-wheel, substantially as set forth andillustrated.

3. An improved scraper for wheels of ageffectively freed from theclinging dirt and ricultural implements, consisting in a disk -my handin presence of two subscribing wit- HBSSGS.
